Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the photoactive system is activated during production to enable data transmission and electrical connection for alignment, then the alignment accuracy can be achieved, but the production time increases and costs increase
Solution Approach 1:
The patent uses a test structure as a copy or substitute for the photoactive system itself. Instead of activating the photoactive system to capture images, a separate test structure with identical optical characteristics is used. This test structure can be imaged without electrical connection, eliminating the time-consuming activation process while maintaining alignment accuracy.
Solution Approach 2:
The test structure acts as an intermediary between the imaging device and the photoactive system. It transfers the optical alignment requirements to the imaging device without requiring the photoactive system to be activated. The test structure mediates the alignment process by providing a passive target that can be imaged using simple optical means.
2Manufacturing precision
If electrical connections and data transmission are established for producing an activated photoactive system, then the system can be aligned and tested, but the hardware complexity and production cost increase
Solution Approach 1:
The patent extracts the alignment function from the photoactive system itself and transfers it to a separate test structure. By removing the requirement for the photoactive system to be activated during alignment, the need for electrical connections, power supply hardware, and data transmission systems is eliminated. Only simple optical imaging hardware remains.
Solution Approach 2:
The patent replaces the electrical and electronic systems (power supply, data transmission) with a purely optical-mechanical system. The alignment is achieved through optical imaging of the test structure using the imaging device, without any electrical connection to the photoactive system. This substitution dramatically reduces hardware complexity.
3Productivity
If the photoactive system is activated for production with low image frequency, then the system can be manufactured, but the production speed decreases
Solution Approach 1:
The test structure is prepared in advance and can be imaged immediately without waiting for photoactive system activation. The imaging device can capture images of the test structure at high speed from the beginning of the production process, eliminating the initial activation delay and enabling faster production cycles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces production costs and time while enhancing image quality by allowing simultaneous or sequential production of multiple photoactive systems with improved alignment accuracy and efficiency.
Implementation Method 1
The at least one imaging arrangement has a beam passage plane and an optical axis and is designed to generate and in particular to shape electromagnetic beams which run along a beam path and pass through the imaging arrangement in the beam passage plane
Implementation Method 2
The imaging arrangement is designed to image an evaluation image of a photoactive arrangement of the photoactive system to be produced and/or of a test structure using the electromagnetic rays reflected by the photoactive arrangement in a first focal plane of the imaging arrangement
Implementation Method 3
the first holding plane of the first holding device is arranged relative to the second holding plane of the second holding device such that the optical arrangement insertable into the first holding device focuses the beam path of the electromagnetic rays in a focal plane
